Definitions
- the present invention relates to a method for measuring cholesterol in high-density lipoproteins, eliminating the necessity of pretreatments such as centrifugal separation and effectively providing simple analytical method while requiring only small amounts of a sample.
- Serum lipids such as cholesterols are bound to apoproteins and form lipoproteins.
- Lipoproteins are categorized into chylomicrons, very low-density lipoproteins, low-density lipoproteins (LDLs), and high-density lipoproteins (HDLs) based on differences in physical properties.
- LDLs are known to be atherogenic
- HDLs are known to have anti-atherogenic action.
- HDL cholesterol is measured after separating HDLs from other lipoproteins using an ultracentrifugation.
- lipids are stained after they are isolated by electrophoresis, and the strength of color development is measured.
- these methods all involve problems such as intricate procedures, inability to handle many samples, etc., and therefore, they have not been used routinely in clinical laboratories.
- the most widely used method for measuring cholesterol in HDLs in clinical laboratories is a precipitation method.
- a precipitant is added to a sample to aggregate lipoproteins other than HDLs, the aggregated lipoproteins are precipitated by centrifugation, and cholesterol present in a supernatant containing only HDLs is measured.
- lipoproteins other than HDLs are aggregated in advance, and only the cholesterol in HDLs is enzymatically reacted. Thereafter, enzymes are inactivated, and the aggregated lipoprotein is simultaneously re-dissolved to measure absorption (Japanese Patent Application Laid-open (kokai) No. 6-242,110).
- This method requires addition of reagent at least three times. Therefore, it can be applied to limited autoanalyzers only, raising a drawback regarding range of use.
- use of a high concentration salt is needed. Therefore, this method is not satisfactory from not only the view point of damage to the analytical apparatus, but also of difficulty in disposing the waste reagent.
- an object of the present invention is to provide a method for quantitatively determining cholesterol in high-density lipoproteins which eliminates the necessity of pretreatments such as centrifugal separation, which effectively provides simple mensuration, and which can be applied to a variety of automated analyzers.
- the present inventors have conducted careful studies, and have found that cholesterol in HDLs can be quantitatively determined efficiently using automated analyzers if a sample is subjected to enzymatic mensuration of cholesterol after it is mixed with a surfactant and with a substance which forms a complex with lipoproteins other than HDLs, leading to completion of the invention.
- the present invention relates to a method for quantitatively determining cholesterol in high density lipoproteins, characterized in that, mensuration of cholesterol in a sample is performed after a surfactant and a substance which forms a complex with lipoproteins other than HDLs are added to the sample.
- the substance which forms a complex with lipoproteins other than HDLs used in the present invention can be any substance insofar as its affinity to HDLs is different from that to lipoproteins other than HDLs.
- examples of such substances include polyanions such as dextrin sulfate, phosphotungstic acid, and heparin; divalent metal ions such as magnesium ions and calcium ions; water-soluble polymers such as polyethylene glycol; and antibodies to lipoproteins other than HDLs. They can be used singly or in combinations of two or more. Among the possibilities, a combination of a polyanion and a divalent metal ion is preferred.
- the amounts of these substances to be used are not particularly limited, and differ depending on the kinds of substances. It suffices that these substances form complexes together with lipoproteins other than HDLs at the time of mensuration. Coagulation may or may not occur.
- concentration of polyanion be 0.02 to 2 % by weight, and that of the divalent metal ion be 10 to 500 mM, after they are admixed with the sample. Particularly preferred is the case where concentration of polyanion is 0.05 to 1% by weight and that of divalent metal ion is 20 to 200 mM.
- the surfactant used in the present invention preferably has the inhibitory effect on the interaction between the enzymes used for the detection of cholesterol and lipoproteins, or in other words, the surfactant preferably does not dissolve lipoproteins.
- surfactants include polyoxyethylene alkylethers, polyoxyethylene alkylphenylethers, polyoxyethylene - polyoxypropylene condensation products, polyoxyethylene alkylether sulfates, and alkyl benzene sulfonates.
- polyoxyethylene alkylethers include polyoxyethylene cetylether (HLB 14) (as commercial products, there are Emulgen 220 manufactured by Kao Corp., etc.).
- polyoxyethylene alkylphenylethers include polyoxyethylene nonylphenylether (HLB 15) (as commercial products, there are Emulgen 913 manufactured by Kao Corp., etc.).
- polyoxyethylene - polyoxypropylene condensation products include commercially available Pluronic F88 manufactured by Asahi Denka K.K.
- polyoxyethylene alkylether sulfates include sodium polyoxyethylene laurylether sulfate (as commercial products, there are Emal 20C manufactured by Kao Corp., etc.).
- alkyl benzene sulfonates include sodium dodecyl benzene sulfonates.
- surfactants may be used singly or in combinations of two or more. Although their amounts are not particularly limited, that are preferably used in such amounts that concentration after being mixed with a sample is from 0.01 to 5% by weight, particularly preferably from 0.05 to 1% by weight.
- a surfactant and a substance which forms a complex with lipoproteins other than HDLs are first added to a sample.
- the two materials may be added as one reagent after being blended, or they may be added as two separate reagents.
- the sample to which has been added a surfactant and a substance which forms a complex with lipoproteins other than HDLs is subjected to a direct determination of cholesterol. That is, no pretreatment such as centrifugation is required.
- Any known enzymatic method may be used for measuring cholesterol.
- cholesterol esterase and cholesterol oxydase may be combined and used as enzyme reagents.
- cholesterol esterase and cholesterol dehydrogenase may be combined.
- methods employing a combination of cholesterol esterase and cholesterol exidase are preferred.
- the amount of signals within a certain period of time is measured, thereby determining the concentration of cholesterol.
- signal amounts between two fixed points of time after addition of enzyme may be compared (2 point method).
- a sample with known HDL value is analyzed similarly.
- the method for determining cholesterol in the final stage following addition of enzyme reagent, etc. is not particularly limited.
- an absorption analysis in which peroxydase and a chromogen are combined may be used as well as methods detecting coenzymes or hydrogen peroxide.
- cholesterol in HDLs can be effectively determined by a simple method. It does not require any pretreatments such as centrifugal separation. Also, since this method provides specific measurement with a small amount of sample and simple operation, it can be adopted in a variety of automated analyzers. Thus, the method is very useful in the field of clinical assays.
